Reasons/evidence why glass tanks are bad...

Hello all. I have been searching on here all day trying to find somewhere that there is solid evidence that glass tanks and aquariums are bad for guinea pigs. I KNOW they are I'm trying to convince a friend that they are. I have given her this website and forum but she refuses to look at it. So I was hoping someone could link to a place that listed all the reasons why aquariums are bad for guinea pigs. I did a forum search and there were over like 2000+ posts with the word aquarium in it and I've gone through like 50+ posts and can't do it anymore with my SLOW internet connection. If you can find or know of a link either here or guinealynx I would really appreciate if you could post it. Then I can send it off to my friend and HOPEFULLY convince her that 3 adolescent male guinea pigs CANNOT be housed in a 20 gallon aquarium. O and they are making eachother bloody and she "doesn't know why". AGGG! Some people just are unwilling to listen but I want to try to give her as much info as possible... Thank you guys!!!

Yes I understand that. I am looking for an actual list if there is one. I am perfectly capable of listing the basics but was looking for reasons other than too small and not enough air flow... Or a medical thread or something. Thanks

Re: Reasons/evidence why glass tanks are bad...

It states never to house guinea pigs in an aquarium because of the poor ventilation.. There's even a downloadable version that you can print out.. I know it's only one sentence, but it's a relative strong one (cos it says 'never') by an authoritative body in the ASPCA ,so I hope it can still be of significant help..

I really cannot stand it that some people refuse to seek proper information and think whatever they do goes.. You'd really have to be some person to be like that...

It's me again

I know it's not a list either but I found a short video you could show her as many people are more receptive to watching a video over reading.

If you go to youtube and search for 'pet guinea pig housing', there is a video by expert village featuring an exotic animal health tech; another authority figure; who speaks about, well, guinea pig housing. I'm not going to link the video here though because it features a pet store cage.

However, she speaks briefly about why guinea pigs should not be kept in aquariums and also mentions avoiding injury from keeping multiple pigs in a small habitat.
